decent product. not as thick as typical sound deadening but definitely cheaper. and for my application, i didnt need a name brand thicker material. i am putting it on our heat and ac vent and intake pipes during our remodel. sound travels from room to room in our old house through these vents and pipes so a little sound deadening goes a long way
